BACKGROUND

Rolling suitcases that are small enough to carry on many airplanes are commonplace. Some rolling suitcases also have attached shoulder straps so that they can be carried as a backpack. However, these designs have certain limitations.

SUMMARY

Embodiments of the present inventive concepts provide a luggage system that addresses the limitations of the conventional configurations.

In some embodiments, the luggage system can include a removable or detachable portion that can be mounted to a front of a rolling suitcase bag.

In some embodiments, the luggage system can include a removable or detachable portion that can be mounted to a rear of a rolling suitcase bag, opposite the front.

In some embodiments, the removable or detachable portion positioned at the front and/or back can be mounted to a suitcase unit that is not rolling.

In some embodiments, the system can include a checkpoint-friendly configuration per TSA regulations.

In some embodiments, a detachable backpack, briefcase, tote, or similar bag can be included in the system as the removable portion.

In some embodiments, the removable portion can be relatively smaller, and used separately from, and independently of, the larger, suitcase bag, when detached. For example, the removable portion can be taken to meetings or used to carry items when touring a destination location, without having to bring the entire suitcase along.

In some embodiments, a system incorporating the features of the present inventive concepts enables a traveler to travel with only one bag. The system is easier to manage by a traveler—leaving one hand free to attend to other items, or both hands free if the entire system is worn as a backpack

In some embodiments, a system incorporating the features of the present inventive concepts allows for passage through TSA security checkpoints in a more traveler-friendly procedure, that can be relatively quicker and easier.

In some embodiments, a system incorporating the features of the present inventive concepts allows for a single bag to be carried and stowed in an airplane, whether under the seat or in an overhead rack, in a manner that is relatively easier and simpler. In some embodiments, the system is configured to qualify as a carry-on bag, in view of United States' requirements for carry-on bags. In some embodiments, the system is configured to qualify as a carry-on bag, in view of international requirements for carry-on bags.

In some embodiments, a system incorporating the features of the present inventive concepts allows for the improvement of the one-bag travel experience for travelers, so that they can travel efficiently with a single, fairly small, carry-on piece of luggage.

As noted above, it would be helpful if the single piece of luggage could be separated at certain points along the journey, so that excursions to meetings or tourist sites could be accomplished in more traveler-friendly fashion, or so that items could be more readily accessed in flight.

In some embodiments, a luggage system is comprised of at least three detachable parts: 1. A “rear unit” or “suspension unit” which may include backpack straps and a compartment which can carry a computer, or a suit, or other fairly flat objects such as files, or may contain a handle or a shoulder strap or both so that when separated it can be carried as a briefcase or tote, 2. A “middle unit” or “suitcase unit” which can carry clothes, toiletries, and/or a variety of other objects, 3. A “front unit”, which, among other embodiments, can have quick-access pockets for storing items in an organized manner. The “rear unit” and the “front unit” can be independently attached or unattached to the “middle unit”. Once unattached from the “middle unit”, the “front unit” and the “back unit” can then be attached together, to form, among other embodiments, a smaller backpack or “daypack”, or alternatively, among other embodiments, a briefcase or tote. Alternatively, both the “front unit” and the “back unit” may be used independently (for example, the “back unit” can be used as a slim backpack that is constructed and arranged to carry a computer or other items. In some embodiments, the “front unit” can be constructed and arranged to independently be hung on an airplane seat to provide easy access to items (such as a tablet, book, headphones, etc., for example) during flight.

In some embodiments, a hip-belt can be included on the “suspension unit”. In some embodiments, the hip belt can be hidden or folded behind a padded panel designed to make the back of the wearer feel more comfortable when the backpack is worn. This hip-belt can then be pulled out from behind the panel by means of a loop attached to the hip-belt, making it easy to grab while wearing the pack, as opposed to currently available packs requiring a user to remove the pack in order to pull out the hip belt. This “pull out while wearing” feature is further enhanced by a crease in the hip belt on each side of the pack, so that, when the belt is stored, it folds to the correct location for the loop to be easily grabbed and pulled.

DETAILED DESCRIPTION

Reference will now be made in detail to the present embodiments of the technology, examples of which are illustrated in the accompanying drawings. Similar reference numbers may be used to refer to similar components. However, the description is not intended to limit the present disclosure to particular embodiments, and it should be construed as including various modifications, equivalents, and/or alternatives of the embodiments described herein.

It will be understood that the words “comprising” (and any form of comprising, such as “comprise” and “comprises”), “having” (and any form of having, such as “have” and “has”), “including” (and any form of including, such as “includes” and “include”) or “containing” (and any form of containing, such as “contains” and “contain”) when used herein, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.

It will be further understood that, although the terms first, second, third etc. may be used herein to describe various limitations, elements, components, regions, layers and/or sections, these limitations, elements, components, regions, layers and/or sections should not be limited by these terms. These terms are only used to distinguish one limitation, element, component, region, layer or section from another limitation, element, component, region, layer or section. Thus, a first limitation, element, component, region, layer or section discussed below could be termed a second limitation, element, component, region, layer or section without departing from the teachings of the present application.

It will be further understood that when an element is referred to as being “on”, “attached”, “connected” or “coupled” to another element, it can be directly on or above, or connected or coupled to, the other element, or one or more intervening elements can be present. In contrast, when an element is referred to as being “directly on”, “directly attached”, “directly connected” or “directly coupled” to another element, there are no intervening elements present. Other words used to describe the relationship between elements should be interpreted in a like fashion (e.g. “between” versus “directly between,” “adjacent” versus “directly adjacent,” etc.).

It will be further understood that when a first element is referred to as being “in”, “on” and/or “within” a second element, the first element can be positioned: within an internal space of the second element, within a portion of the second element (e.g. within a wall of the second element); positioned on an external and/or internal surface of the second element; and combinations of one or more of these.

As used herein, the term “proximate” shall include locations relatively close to, on, in and/or within a referenced component, anatomical location, or other location.

Spatially relative terms, such as “beneath,” “below,” “lower,” “above,” “upper” and the like may be used to describe an element and/or feature's relationship to another element(s) and/or feature(s) as, for example, illustrated in the figures. It will be further understood that the spatially relative terms are intended to encompass different orientations of the device in use and/or operation in addition to the orientation depicted in the figures. For example, if the device in a figure is turned over, elements described as “below” and/or “beneath” other elements or features would then be oriented “above” the other elements or features. The device can be otherwise oriented (e.g. rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

The terms “reduce”, “reducing”, “reduction” and the like, where used herein, are to include a reduction in a quantity, including a reduction to zero. Reducing the likelihood of an occurrence shall include prevention of the occurrence.

The term “and/or” where used herein is to be taken as specific disclosure of each of the two specified features or components with or without the other. For example, “A and/or B” is to be taken as specific disclosure of each of (i) A, (ii) B and (iii) A and B, just as if each is set out individually herein.

In this specification, unless explicitly stated otherwise, “and” can mean “or,” and “or” can mean “and.” For example, if a feature is described as having A, B, or C, the feature can have A, B, and C, or any combination of A, B, and C. Similarly, if a feature is described as having A, B, and C, the feature can have only one or two of A, B, or C.

The expression “configured (or set) to” used in the present disclosure may be used interchangeably with, for example, the expressions “suitable for”, “having the capacity to”, “designed to”, “adapted to”, “made to” and “capable of” according to a situation. The expression “configured (or set) to” does not mean only “specifically designed to” in hardware. Alternatively, in some situations, the expression “a device configured to” may mean that the device “can” operate together with another device or component.

It is appreciated that certain features of the disclosure, which are, for clarity, described in the context of separate embodiments, may also be provided in combination in a single embodiment. Conversely, various features of the disclosure which are, for brevity, described in the context of a single embodiment, may also be provided separately or in any suitable sub-combination. For example, it will be appreciated that all features set out in any of the claims (whether independent or dependent) can be combined in any given way.

It is to be understood that at least some of the figures and descriptions of the disclosure have been simplified to focus on elements that are relevant for a clear understanding of the disclosure, while eliminating, for purposes of clarity, other elements that those of ordinary skill in the art will appreciate may also comprise a portion of the disclosure. However, because such elements are well known in the art, and because they do not necessarily facilitate a better understanding of the disclosure, a description of such elements is not provided herein.

Terms defined in the present disclosure are only used for describing specific embodiments of the present disclosure and are not intended to limit the scope of the present disclosure. Terms provided in singular forms are intended to include plural forms as well, unless the context clearly indicates otherwise. All of the terms used herein, including technical or scientific terms, have the same meanings as those generally understood by an ordinary person skilled in the related art, unless otherwise defined herein. Terms defined in a generally used dictionary should be interpreted as having meanings that are the same as or similar to the contextual meanings of the relevant technology and should not be interpreted as having ideal or exaggerated meanings, unless expressly so defined herein. In some cases, terms defined in the present disclosure should not be interpreted to exclude the embodiments of the present disclosure.

In some embodiments, the third body 300 comprises a third storage region 320, a second portion 420 of the first attachment mechanism 400, and a second portion 470 of the second attachment mechanism 450. In the embodiment shown in FIG. 1, the third body 300 is configured as a rolling suitcase, comprising at least one wheel 310 and at least one handle 315. In some embodiments, the third body 300 does not comprise any wheels. In some embodiments, the third body 300 comprises a different number of wheels 310 than the embodiment shown in FIG. 1. In some embodiments, the third body 300 comprises wheels 310 at one side of the third body 300, so that the rolling suitcase can be pitched at an angle using the handle 315 and rolled. In some embodiments, the third body 300 comprises wheels 310 at one side of a lower portion of the third body 300, for example two wheels coupled to the third body with horizontal axles, and feet 380 at the other side of the lower portion, so that the rolling suitcase can be pitched at an angle using the handle 315 to operate in a rolling mode, or rested on its feet 380 in a stationary mode. In some embodiments, the third body 300 comprises wheels 310 at both sides of the third body 300, for example four pivoting wheels coupled to the third body 300 vertical axles, so that the rolling suitcase can be freely rolled in any direction using the handle 315.

The at least one handle 315 may be retractable. In some embodiments, the at least one handle 315 may extend and retract by way of a telescoping mechanism. In some embodiments, the third body 300 is absent a handle. In some embodiments, the at least one handle 315 is fixed and non-retractable. In some embodiments, the third body 300 comprises handles 315 positioned at side portions of the third body 300, for example at opposite side portions. In some embodiments, an access cover is provided to cover the at least one handle 315, when retracted. In such an embodiment, the access cover comprises a zipper or similar access mechanism for accessing the handle 315.

In the embodiment depicted in FIG. 1, the third storage region 320 can be opened and/or closed, and/or otherwise accessed, with a third access zipper 322. In other embodiments, the third storage region 320 can be opened and/or closed, and/or otherwise accessed, using other types of access mechanisms including, but not limited to, clasps, levers, straps, or buttons.

In the embodiment shown in FIG. 1, the first portion of the first attachment mechanism 410 of the first body 100 is coupled to the second portion of the first attachment mechanism 420 of the third body 300. In the embodiment shown in FIG. 1, the first portion of the second attachment mechanism 460 of the second body 200 is coupled to the second portion of the second attachment mechanism 470 of the third body 300.

In the embodiment shown in FIG. 1, the first body 100 and the second body 200 are attached to the third body 300 by attachment mechanisms 400, 450, for example in the form of attachment zippers. In some embodiments, the attachment zippers are designed to be the same size and attached in the same shape to both the first body 100 and the second body 200. In other embodiments, first 100 and second 200 bodies could also be attached to each other by other types of attachment mechanisms, such as Velcro, clips, straps, hooks, bands with elastic properties, or other types of fasteners or attachment mechanisms.

By configuring the first and second attachment mechanisms 400, 450 to be the same size, shape or length, a modular system can be provided. In the embodiment shown in the side view of FIG. 1, and, further referring to the perspective views of FIGS. 1A1 and 1A2, a front portion of a backpack in the form of body 200, can be separated from the system 1000, in this case, separated from the third body 300 of the system 1000, by separating the second attachment mechanism 450. Similarly, a rear portion of a backpack, in the form of body 100, can likewise be separated from the system, in this case, separated from the third body 300 of the system 1000 by separating the second attachment mechanism 400.

Once separated, the first body 100 can be coupled directly to the second body 200. In particular, the first portion 410 of the first attachment mechanism 400 is configured to couple to the first portion 460 of the second attachment mechanism 450. In a case where the first and second attachment mechanisms 400, 450 comprise zippers, the first portion 410 of the first attachment mechanism 400 may include a zipper slider and zipper retainer box, while the second portion 420 of the first attachment mechanism 400 may include a zipper pin that mates with the zipper slider and zipper retainer box of the first portion 410 of the first attachment mechanism 400. Similarly, the first portion 460 of the second attachment mechanism 450 may include a zipper pin, while the second portion 470 of the second attachment mechanism 450 may include a mating zipper slider and zipper retainer box that corresponds to the first portion 460 of the second attachment mechanism 450. As shown in FIG. 1A2, as a result, the first body 100 can be coupled directly to the second body 200. In this example, the coupled first body 100 and second body 200 provide a daypack configuration, with the first body 100 providing the utility of a full suspension 110 along with a first pack volume at the first storage region 120, and with the second body 200 providing a second pack volume at the second storage region 220.

To accommodate this arrangement, the geometries of the first and second portions 410, 420 of the first attachment mechanism 400 and the geometries of the first and second portions 460, 470 of the second attachment mechanism 450 are arranged to match. In the case of the first and second attachment mechanisms being in the form of zippers, the matching zippers can be configured to have corresponding positional geometries, corresponding lengths, mating zipper teeth, and the like.

In some embodiments, the zipper tape of each of the first and second portions 410, 420, 460, 470 is coupled to portions of respective bodies 100, 200, 300 so that the zipper teeth extend in a direction away from the body 100, 200, 300 to which it is coupled, for mating with zipper teeth of a corresponding portion of a corresponding body 100, 200, 300. In some embodiments the zipper tape is coupled to the body 100, 200, 300 so that the zipper teeth extend in a direction that is substantially perpendicular to the body 100, 200, 300.

FIGS. 1B1 and 1B2 are perspective views of examples of matching zipper geometries for the first and second portions 410, 420 of the first attachment mechanism 400 and the first and second portions 460, 470 of the second attachment mechanism 450 in accordance with an embodiment of the present inventive concepts. In this example embodiment, the zippers of each of the first and second attachment mechanisms 400, 450 comprise a single zipper. The first and second portions 410, 420 of the first attachment mechanism 400 and the first and second portions 460, 470 of the second attachment mechanism 450 are coupled to the respective bodies in a generally arched-shaped, or upside-down-U-shaped, configuration. The right-side legs of each zipper portion 410, 420, 460, 470 have the same height Hz1 and the left-side legs of each portion 410, 420, 460, 470 have the same height Hz2. In some embodiments, the heights of the right-side legs Hz1 and the heights of the left-side legs Hz2 are in turn equal to each other, i.e., Hz1=Hz2. In addition, the horizontal portions of each zipper portion 410, 420, 460, 470 have the same width Wz.

By configuring the portions 410, 420, 460, 470 of the attachment mechanisms 400, 450 to have similar geometries, the first and second bodies 100, 200 can be separated from the third body 300 and re-attached to each other, as shown in FIG. 1A2.

Other configurations of the attachment mechanisms are equally applicable to the principles of the present inventive concepts.

With reference to the perspective view of FIG. 1C, in this embodiment, the zipper portions 410 a, 420 a, 460 a, 470 a are coupled at a position that is recessed relative to a sidewall of the respective body 100, 200, 300 by a recess amount R. This configuration can operate to protect the coupled zipper from interference.

With reference to the perspective view of FIG. 1D, in this embodiment, the zipper portions 410 b, 420 b, 460 b, 470 b are coupled at a position that is at or near a sidewall of the respective body 100, 200, 300, as in the embodiment of FIG. 1B. However, in the present embodiment, the zipper portions 410 b, 420 b, 460 b, 470 b each comprise three sub-portions 410 b 1, 410 b 2, 410 b 3; 420 b 1, 420 b 2, 420 b 3; 460 b 1, 460 b 2, 460 b 3; 470 b 1, 470 b 2, 470 b 3. The geometry and positioning of the three sub-portions match each other as described herein.

With reference to the perspective view of FIG. 1E, in this embodiment, the zipper portions 410 b, 420 b, 460 b, 470 b are coupled at a position that is at or near a sidewall of the respective body 100, 200, 300, as in the embodiment of FIG. 1B. However, in the present embodiment, the zipper portions 410 b, 420 b, 460 b, 470 b each comprise two sub-portions 410 c 1, 410 c 2; 420 c 1, 420 c 2; 460 c 1, 460 c 2; 470 c 1, 470 c 2. The geometry and positioning of the two sub-portions match each other as described herein.

As described herein, the front 200 and back 100 units can each be independently attached to the suitcase unit 300, creating an integrated unit that can be carried as a single piece, for example carried by the suspension 110 as a single piece. Alternatively, the front 200 and back 100 units can be separated from the suitcase unit 300 and joined together by the first portion 410 of the first attachment mechanism 400 and the first portion 460 of the second attachment mechanism 450 create a backpack, which can be used and worn independent of the suitcase unit 300, as described herein at least in connection with the embodiments of FIGS. 1A2 and 5-7. Note also that both the front unit 200 and the back unit 100 could also be used independently of each other, so that the system can be deployed as three separate, functional units 100, 200, 300, for example as illustrated at least in the embodiments of FIGS. 1B, 1C, 1D, 1E.

In other embodiments, attachment mechanisms 400, 450 other than zippers can be employed. For example attachment mechanisms 400, 450 in the form of such as clasps, levers, straps, and the like, or other suitable mechanisms for removably coupling the first, second and third bodies 100, 200, 300 can be employed. In such a configuration, by configuring the positions of the mating attachment mechanisms 400, 450 to be of the same configuration, geometry, and/or position for each portion, a modular system can be provided.

Returning to the embodiment of FIG. 1, the rolling system 1000 can operated to be rolled as a rolling bag. In the rolling mode, the shoulder straps 140 and hip belt 150, 160 of the suspension 110 can be stowed at or behind a back panel 170 of the first body 100. Alternatively, the system 1000 in its entirety can be worn as a backpack, with both the suspension unit 100 and the front unit 200 attached to the third body, or suitcase unit 300.

According to the TSA (Transportation Security Administration), a backpack is to exhibit the following to be designated as “checkpoint friendly”, so that a computer can be screened without being removed from the bag:

For a bag to be considered checkpoint friendly it should meet the following standards: A designated laptop-only section

-   -   The laptop-only section completely unfolds to lie flat on the         X-ray belt     -   No metal snaps, zippers or buckles inside; underneath or on top         of the laptop-only section     -   No pockets on she inside or outside of the laptop-only section     -   Nothing packed in the laptop-only section other than the         computer itself.

Embodiments of the rear unit 100 can incorporate the requirements of the checkpoint-friendly specifications, as partially shown in FIG. 12:

-   -   The access zipper 122 of the rear unit 100, which is located at         the REAR of the rear unit (close to the padding for the back),         unzips on three sides (left side, right side, and top), while         the bottom side forms a hinge 800 with the rest of the rear unit         100. Note that only one zipper is needed to accomplish this         design.     -   The laptop only section will then be a slim pocket 810 (not         shown in the diagram) in the flap that folds out, into which the         computer will be placed. This may be secured by a Velcro strap         815 or other closure device that does not use metal snaps,         zippers, or buckles.     -   While nothing but the computer will be stored in the laptop-only         section mentioned above, other items (such as cables, files,         discs, clothing, etc., may be stored in the remainder of the         cavity of the rear unit 100 not occupied by the computer. This         is advantageous compared to a design that requires only the         computer and nothing else to be stored in the entire cavity.     -   While straps and buckles are positioned at on the sides of the         rear unit 100 in order to attach it to the suitcase 300 or the         front unit 200, these are not to be metal, and, since they are         placed on the side of the unit, do not interfere with the         checkpoint friendly designation.

FIG. 13 is a side perspective view of an embodiment of the TSA-friendly first body 100 in the open position in accordance with the present inventive concepts.

FIG. 14 is a side view of an embodiment of the TSA-friendly first body 100 coupled to the second body 200 and the third body 300 in accordance with the present inventive concepts.
